Electric four-way adjusting steering pipe column mechanism and adjusting method thereof

Abstract

The invention discloses an electric four-way adjusting steering pipe column mechanism and an adjusting method thereof. The electric four-way adjusting steering pipe column mechanism comprises a pipe column assembly, a swinging pipe assembly, a steering column bracket, a steering column assembly, a displacement motor, a displacement sensor, a displacement worm wheel and worm speed reducer, a displacement worm base, an angle motor, an angle sensor, an angle worm wheel and worm speed reducer, an angle worm base, a controller and an adjusting button. According to the electric four-way adjusting steering pipe column mechanism disclosed by the invention, the displacement motor drives the pipe column assembly and the swinging pipe assembly to slide, so that the adjustment of the steering pipe column in the front direction and in the rear direction is realized; the angle motor drives the swinging pipe assembly and the steering column bracket to rotate, so that the adjustment of the steering pipe column in the upper direction and in the lower direction is realized; through the adoption of the displacement worm wheel and worm speed reducer and the angle worm wheel and worm speed reducer, the adjustment of torque transmission is realized; a locking mechanism in a manual adjusting steering pipe column is replaced by a worm because of the own locking effect of the worm, so that the complexity degree of the structure of the steering pipe column mechanism is effectively reduced. The electric four-way adjusting steering pipe column mechanism disclosed by the invention is simple in structure, low in occupied space and convenient to operate, the adjusting function is good, and the safety and the reliability of a vehicle are improved.

Description

technical field [0001] The invention relates to an automobile steering column, in particular to an electric four-way adjustment steering column mechanism and an adjustment method thereof. Background technique [0002] With the continuous development of my country's automobile industry and the continuous improvement of automobile quality, people have higher and higher requirements for the performance of automobile parts, and the automobile steering column assembly, as a component connecting the steering wheel and the steering gear, its role is not only to transmit At present, in order to ensure the safety of the driver, and at the same time to control the steering more comfortably and reliably, the vehicle usually requires the use of a reliable and safe adjustment device on the steering control mechanism, and an adjustable steering column tube. In order to meet the driver's different driving posture and body to the best control position of the steering wheel, as well as the dr...

AI Technical Summary

Problems solved by technology

[0003] At present, most domestic four-way adjustable steering columns use manual adjustment devices with mechanical locking mechanisms, but there are complex structures, high machining accuracy requirements for parts, large installation space, limited holding force of locking mechanisms, and faster fatigue wear. At the same time, there are shortcomings such as inconvenient operation and unreliable adjustment performance in the driver's experience.
